Closed-Form Expressions of Upper Bound for Polarization-MDCSK System [PDF]

Entropy, 2023
The performance analysis of polarization M-ary differential chaos shift keying (P-MDCSK) has been expressed using a tight upper bound with the Q-function. However, evaluating the Q-function directly is not a closed expression and there has been less work

Temperature upper bound of an ideal gas [PDF]

Heliyon
We study thermodynamics of a heat-conducting ideal gas system. The study is based on i) the first law of thermodynamics from action formulation which expects heat-dependence of energy density and ii) the existence condition of a (local) Lorentz boost ...

On polytopal upper bound spheres [PDF]

Mathematika, 2012
Generalizing a result (the case $k = 1$) due to M. A. Perles, we show that any polytopal upper bound sphere of odd dimension $2k + 1$ belongs to the generalized Walkup class ${\cal K}_k(2k + 1)$, i.e., all its vertex links are $k$-stacked spheres.

Upper Tail Bounds for Stars [PDF]

The Electronic Journal of Combinatorics, 2020
For $r \ge 2$, let $X$ be the number of $r$-armed stars $K_{1,r}$ in the binomial random graph $G_{n,p}$.  We study the upper tail ${\mathbb P}(X \ge (1+\epsilon){\mathbb E} X)$, and establish exponential bounds which are best possible up to constant factors in the exponent (for the special case of stars $K_{1,r}$ this solves a problem of Janson and ...

Review of the Upper Bound Method for Application to Metal Forming Processes

Metals, 2022
In this paper, we review the upper bound method in plasticity with special reference to metal forming processes. We focus on the method itself, solution methods, and restrictions of the upper bound method.

GUBS Upper Bound Solver (Extended Abstract) [PDF]

Electronic Proceedings in Theoretical Computer Science, 2017
In this extended abstract we present the GUBS Upper Bound Solver. GUBS is a dedicated constraint solver over the naturals for inequalities formed over uninterpreted function symbols and standard arithmetic operations. GUBS now forms the backbone of HoSA,

Estimation Method for Upper Bound of General Pattern Index Based on Modified BPSO [PDF]

Jisuanji gongcheng, 2018
A general pattern index upper bound estimation method based on modified Binary Particle Swarm Optimization (BPSO) algorithm is proposed to estimate the boundary value estimation problem in constrained frequent pattern mining.According to the ...

Variational Inference via Rényi Bound Optimization and Multiple-Source Adaptation

Entropy, 2023
Variational inference provides a way to approximate probability densities through optimization. It does so by optimizing an upper or a lower bound of the likelihood of the observed data (the evidence).
